The Toyota Prius is a hybrid vehicle with inverters suitable for DIY EVs
The Toyota Prius is a hybrid vehicle with inverters that are highly suitable for DIY EVs. Its inverters are attractive for DIY EVs due to their large part availability, affordability, durability, performance, and ease of repurposing. Priuses have been manufactured in large numbers over the past 20 years, so spare parts are easy to find and inexpensive. Prius inverters are available for around $150 from scrap yards.
Toyota Prius inverters are also durable and reliable. The inverters are designed to handle fault conditions gracefully, with many inputs and outputs. They are rated for 50kW output but have been tested to handle 600v, 350+A for MG2 inverter, 250+A for MG1 inverter, and a total of 360kW (480hp). The Gen 2 Prius (2004-2009 models) comes with two high-power inverters, one for each of the two motors: MG1 (starter) and MG2 (drive motor).
The Prius inverters are also easy to repurpose. Emulating the original ECU seems reasonably feasible, and there are add-on controllers available that can replace the vehicle's wiring harness and ECU. The Gen 3 Prius inverters can also be used to step up or down the input voltage to charge the high-voltage battery in the car.
There are various companies that offer products and services related to Prius inverters, such as PlugOut Power LLC, which offers inverters specifically for Toyota hybrids. There are also companies like GoaMotors that offer electric inverter cooling pump wire connector plug harnesses suitable for Toyota Prius models from 2004 to 2009.
Overall, the Toyota Prius's hybrid system, with its inverters, makes it an excellent candidate for DIY EVs, with its wide availability, affordability, and ease of repurposing.

The Prius Gen2 inverter can be repurposed to generate AC outlet voltages for off-grid use
The Toyota Prius is a hybrid vehicle with a range of benefits, including large part availability, affordability, durability, and ease of repurposing. The Prius Gen2 inverter can be repurposed to generate AC outlet voltages for off-grid use.
The Prius Gen2 inverter has two high-power inverters for the two motors MG1 (starter) and MG2 (drive motor). The MG1 inverter can handle 250 amps, while the MG2 inverter can handle 350 amps. The Prius inverter is a VFD with the right software to control a 3 Phase AC motor.
To repurpose the Prius Gen2 inverter, the CLK and ITE signals must be activated by supplying 12V to IG and >40V to the main DC power supply inlet. Additionally, the STB must be connected to GND, and appropriate 10-byte messages must be sent to the inverter on ETI. The inverter also has a buck/boost converter that can boost the battery pack voltage from ~200V to 600V for the motors.
There are a few considerations when working with the Prius Gen2 inverter. The inverter is liquid-cooled, requiring a circulating pump and radiator. The wire colours on the 32-pin "i10" connector may not match, so it is important to identify the correct wires by their unique colour schemes and shielded cables.
Some people have successfully used the Prius Gen 2 inverter for off-grid power generation, but there are also alternative methods and considerations to explore. One alternative method involves using a different ECU to run the engine like a normal car engine and rectifying the AC output to DC for battery charging. Another user mentions the possibility of using a boost converter to step up the battery voltage to allow the inverter to produce higher voltages without a transformer. It is important to note that the laws and regulations for DIY electrical work vary by country and state, and safety precautions must be considered when working with high voltages.

The Prius Gen2 inverter controller has a unique colour scheme on the wiring harness side
The Prius Gen2 inverter controller is an open-source board designed to repurpose the Toyota Prius Gen2 Inverter by replacing the essential components of the Prius wiring harness and electronics. It runs the OpenInverter.org software for vehicle control. The Gen2 Prius (2004-2009 model years) has a variety of useful components inside the inverter package: 2 high-power inverters, for the 2 motors MG1 (starter) capable of handling 250 amps, and MG2 (drive motor) capable of handling 350 amps.
The Prius Gen2 inverter has been used with moderate success to generate AC outlet voltages for off-grid use. The inverter is liquid-cooled, with coolant entering at the front and exiting the rear of the inverter housing from the o-ring port connected to the Hybrid Synergy Drive (HSD) cooling system reservoir. A circulating pump and radiator are needed to use Toyota inverters.
The onboard DC-DC Converter is powered by the high-voltage traction battery to supply 12v and up to 100A for low-voltage automotive components and 12-volt battery maintenance. Direct control of the converter is simple, only one 12v wire connected to Pin#1 of connector "C5" is necessary to activate it, but a second input can be added at Pin#4 to enhance control.

The onboard DC-DC converter is powered by the high-voltage traction battery, supplying 12v for low-voltage components
The Prius is a hybrid vehicle manufactured by Toyota. The Prius Gen2 model, produced between 2004 and 2009, is notable for its inverter, which has made it attractive for DIY EV projects. The Prius inverter is durable, affordable, and readily available, with high-power inverters for the two motors, MG1 (starter) and MG2 (drive motor).
The onboard DC-DC converter plays a crucial role in electric vehicles (EVs). It is responsible for converting high-voltage DC power from the lithium-ion battery into low-voltage DC power, supplying 12V for low-voltage components. This conversion is essential because while the travel motor requires high voltage to operate, other components, such as the ECU, cameras, lights, and audio system, function on low voltage.
In the context of the Prius Gen2, the onboard DC-DC converter is powered by the high-voltage traction battery. It supplies 12V for low-voltage automotive components, including the 12V battery maintenance. To activate the converter, a 12V wire connection to Pin#1 of connector "C5" is required. This simple direct control allows the converter to produce an output voltage of 13.2-15.2 Vdc, equivalent to a 12V alternator or generator.
The DC-DC converter consists of electronic components such as a control chip, inductor coil, diode, transistor, and capacitor. It is designed to have specific properties, including high voltage withstand capability, large current handling, low loss, high resistance to heat, compact size, and high precision. These characteristics enable the converter to efficiently supply power to the various low-voltage components in an EV, ensuring optimal performance, efficiency, and safety.
The DC-DC converter is a vital component in electric vehicles, including the Prius Gen2, as it facilitates the necessary voltage conversion for powering low-voltage systems while also contributing to overall vehicle performance and efficiency.
